We recently had a new requirement to use the phonon component of Qt, which on windows requires Visual Studio. I installed VS2008 and ran a compile. There are a stack of problems due to make not working anything like nmake. Since I need to maintain cross-platform I want to test which compiler is being used so that I can make changes as...
I have my own game engine using C++ and OpenGL, but I have models with individual pieces that can be moved, and Im not sure how to animate them without hardcoding it. Are there any libraries that would provide a solution via scripts or IK or some other animation technique without resorting to a game engine such as Ogre? ...
It's been ages since I've written a COM dll. I've made a couple of classes now, that inherit from some COM interfaces, but I want to test it out. I know I have to put a GUID somewhere and then register it with regsvr32, but what are the steps involved? Edit: Sorry, forgot to mention I'm using C++. ...
Hi everybody, I have this long and complex source code that uses a RNG with a fix seed. This code is a simulator and the parameters of this simulator are the random values given by this RNG. When I execute the code in the same machine, no matter how many attempts I do the output is the same. But when I execute this code on two differe...
In his The C++ Programming Language Stroustrup gives the following example for inc/dec overloading: class Ptr_to_T { T* p; T* array ; int size; public: Ptr_to_T(T* p, T* v, int s); // bind to array v of size s, initial value p Ptr_to_T(T* p); // bind to single object, initial value p Ptr_to_T& operator++(); // prefix Ptr_to_T ope...

I'm basically looking for a way to automate typing stuff like the following: cout << "a[" << x << "][" << y << "] =\t" << a[x][y] << endl; Something like: PRINTDBG(a[x][y]); Ideally this would also work for PRINTDBG(func(arg1, arg2)); and even PRINTDBG(if(condition) func(foo);); (which would print e.g. "if(false) func(5)"). ...
Sorry in advance, I'm struggling a bit with how to explain this... :) Essentially, I've got a typical windows coordinate system (the Top, Left is 0,0). If anybody's familiar with the haversine query, like in SQL, it can get all points in a radius based on latitude and longitude coordinates. I need something much simpler, but my math s...

My degree is in Electrical and Computer Engineering but i'm currently employed as a Software Engineer. I took all of the algebra, geometry and calculus classes that one would expect from someone with my degree however I must admit, I think I learned just enough to pass the test but never really saw a use for it and therefore never really...
I talked my team into turning on compiler warnings again. Some how all warnings (-w) were disabled (don't ask...). Most of them are obvious but one of them is really annoying. I get it from my date and time classes which are used in lots of places. Story is really simple. Time is subclass of Date and both of them have their operators def...
I know this is probably general, please bear with me! We've got a program that uses a web camera and, based on what the camera is seeing, runs certain functions. The program runs excellently on MacOS and Linux, and it compiles and it does run on Windows, but a couple of the functions, (including one that iterates pixel by pixel, 640x480...
